Definitions

  • the present invention refers to a land clearing machine, of the type that use a plurality of articulated crushing hammers mounted on a rotor, which act inside a protection housing on which they perform the ripping or crushing, for example, of plant waste.
  • the object of the invention is to achieve a machine with a considerably greater working width - practically double - than conventional land clearing machines, with full operational efficacy and without said measurements or dimensions representing an obstacle when it comes to transferring the machine from one place to another.
  • Land clearing machines known to date have a protection housing, provided with means for coupling to a farm tractor vehicle, a housing accommodating a rotor shaft that carries a plurality of crushing hammers or rippers, said housing being further provided with a ground support roller that establishes the working level of the ripper, which receives the necessary motion for its rotor shaft from the hydraulic circuit of the actual tractor vehicle.
  • the land clearing machine proposed by the invention resolves the above-mentioned problems in a fully satisfactory way, as, thanks to its special design, it is in a position to incorporate two or more rotor shafts, with their respective protection housings, working behind and on both sides of the tractor vehicle, achieving a broad working strip without said shafts proving any obstacle whatsoever during the transporting of the machine, inasmuch as they fold back up to a vertical position in which they do not protrude in the slightest from the sides of the tractor vehicle.
  • the side drive systems that operate the rotors are housed in the interior part of the machine assembly, thereby leaving the sides unobstructed so that they may perform their function efficiently.
  • the modularity or splitting of the rotor also permits better adaptation to the ground surface, especially when this is uneven.
  • the two afore-mentioned rotor shafts may have independent drive instead of there being a direct drive system from one to the other, and their support shaft may be split in its middle section, where a system of connecting rods is established making up a deformable parallelogram, operated by a hydraulic or pneumatic cylinder, so that the afore-mentioned heads may have their relative position adjusted by means of said parallelogram and working strips of varying widths may be achieved in keeping with the specific requirements in every case.
  • the cylinders with which the heads are folded are assisted by respective safety plates, which keep said heads locked in their vertical transport position, thereby preventing them from dropping accidentally or suddenly swivelling sideways due to trouble in the hydraulic circuit supplying these cylinders.
  • the land clearing machine proposed by the invention is structured on the basis of the classic three-point hitch (1), provided with three pairs of lugs (2) for coupling to the tractor vehicle, a hitch (1) which is extended rearwards in sturdy shaft (3) on which is mounted, with the aid of intermediate support (4-4'), the machine drive shaft (5), equipped with the classic power take-off (6) for coupling to the tractor vehicle, a drive shaft (5) which further has the particularity of being the swivel shaft for two heads or housings (7-7') with their respective ground support rollers (8) as well as their respective rotor shafts (9) carrying the classic hammers (10), so that the aforesaid shaft (5) transmits motion to both rotor shafts (9) directly, irrespective of what the position of said rotor shafts (9) is, i.e. the horizontal or working position shown in figure 1, or the inoperative vertical position, after an upward swivel.
  • the heads (7-7') it is feasible for the heads (7-7') to have an adjustable relative position, for which purpose the drive shaft (5) of the previous case disappears and instead the heads (7-7') are provided with respective power take-offs (6-6'), independent of each other, and the support shaft (3) is split into two halves (3-3'), each one of which ends in a flange (15) integral with a plate (15'), so that both plates are related to each other by means of a pair of connecting rods (16), which configure a deformable parallelogram with the afore-mentioned plates (15'), said plates (15') having counterposed extensions (17-17'), between which there extends a hydraulic cylinder (18) that acts diagonally on the aforesaid parallelogram, so that when this takes the form of a rectangle, as represented in figure 3, the two heads (7-7') are the maximum distance apart in a fore-aft direction and they adopt an intermediate position in the transverse direction, and when said parallelogram is deformed in one direction
  • each of the hydraulic cylinders (11-11') with which the heads (7-7') are swivelled from the working position shown in the figures to the vertical transport position is assisted by a safety plate (19), integral at one of their ends with the actual head (7), naturally with the possibility of rotation, and assisted by a guide (20) mounted on the actual body of the cylinder (11-11'), finished at the end with a hole (21) through which the plate (19) may be engaged on a hook (22) on one of the cylinder (11) swivel lugs (13), an engagement which obviously takes place when the cylinder (11) is fully retracted, i.e. in the position for raising the head (7), a position which means that said head (7) is locked irrespective of whether the cylinder (11) may be actuated accidentally or whether a fault may occur in its hydraulic circuit.
